Abstract

A device for measuring a glucose level or some other parameter of living tissue that affects the dielectric properties of the tissue is disclosed. The device comprises an electrode arrangement (5) having a plurality of electrodes (5-i). The signal from a signal source (31) can be applied to the electrode arrangement via a switching assembly (39). The switching assembly (39) is designed to selectively connect a first and a second pattern of the electrodes (5-i) to the signal source, thereby generating a first and a second electrical field with different spatial distribution in the tissue. By using a differential method which relies on measuring the impedance of the electrode arrangement (5) for each field and on suitable subtraction of the measured results, surface effects can be reduced and the focus of the measurement can be offset to a point deeper inside the tissue.
